Contact-limited, ambipolar transport, which describes the drift current behavior of minority carriers not confined to the active layer of double heterostructure injection lasers, is used to predict different behavior than previous calculations for the temperature dependence of the threshold current for lasing. The high-temperature coefficients of some lasers may more easily be explained using the model.
Anthony et al. (1980) studied this question.
